Do you think that the Cadet #2100016020 is a quality toilet? With two teenage boys, we seem to have clogging and overflowing more than usual. I have found this model at Lowe's in my hometown for $222.00 (seat included). I liked the one piece model because of the cleaning advantages (not having to get under the tank). I just want to be sure that while I am replacing my old toilet that I get one that will last me for several year without much hassle. Also, are parts for this toilet hard to find? The man at Lowe's said parts were hard to get.
